Megger-Full Database Driven Portable Appliance Tester Model-PAT45
Operators of electric tools and other electrical equipment must be protected from potentially dangerous flaws in workmanship or wear and tear. The PAT450 is designed to test portable electrical equipment for safe operation. The tests conform to the latest editions of European regulations and standards including VDE0701-0702 and the Code of Practice for the In-Service Inspection and Testing of
Electrical Equipment in the UK.
The PAT450 has a memory capacity for storing up to 10,000 test results, and also 10 A and 25 A earth bond testing. The unit also includes 1.5 kV and 3 kV flash testing, ideal for tool rental outlets and service workshops where flash testing is routine. It has a high duty cycle, with the design tailored to fast testing, easy operation, and all-day use.
The PAT450 features a unique restart, so that when moving the tester from one room to another, it restarts instantly from the same menu where it was unplugged. This is a significant timesaver, allowing more tests per day.
USB communication provides convenient download to a standard USB memory stick. An on-board 10,000 record memory provides interruption-free testing for improved efficiency, with a large QWERTY keypad for fast data entry. The instrument is capable of working with standard barcode scanners and a thermal transfer barcode label printer operating directly from the USB port. Thermal transfer labels are highly resistant, stable and easily available.
Five soft-keys give direct access to frequently-used functions, accelerating navigation through menus and increasing productivity. Both standard and customer configurable test groups are available for fast, flexible asset testing.
Accessories supplied include a combined earth-bond and insulation test lead, an adapter for testing 120 V extension leads, a laptop power supply adapter, and a carry case for convenient product and lead storage. All instruments also include download manager software, to enable data to be converted into a CSV format which can be read directly on a PC using Microsoft® Excel.
TYPE OF TESTS
Earth Bond and Continuity Tests To verify the integrity of exposed metalwork on grounded (Class I) appliances. Test current of 25 A is passed via a remote probe, returning through the Ground pin of the power plug.
Test currents of 10 A and 25 A are available for bond testing. Where sensitive electronic equipment may be damaged by high currents, 200 mA is selectable.
Insulation Test
To check that equipment conductors are isolated from ground – 500 V dc; the live and neutral conductors are linked; and the test voltage is applied between this link and the ground pin. Where an appliance does not have an earth connection (Class II), the remote probe is used to contact anywhere on the external case of the equipment.
Where 500 V may damage sensitive equipment, the PAT450 provides alternative methods of verifying insulation integrity. A lower voltage of 250 V dc is selectable, or alternatives such as a touch current test or substitute leakage test can be performed.
